Orthopositronium lifetime: analytic results in O(alpha) and O(alpha3lnalpha)

Orthopositronium lifetime: analytic results in O(alpha) and O(alpha3lnalpha)

We present the O(alpha) and O(alpha3lnalpha) corrections to the total decay width of orthopositronium in closed analytic form, in terms of basic irrational numbers, which can be evaluated numerically to arbitrary precision.
